A military official at al-Khadim air base in eastern Libya said that a half-dozen Russian planes — some coming from Russia and some from Syria — had arrived carrying military equipment since Dec. 8, when Syrian rebels overthrew Russia’s ally, Bashar al-Assad.

Leaders in Rome fear Moscow's warships could be parked "two steps" from Italian shores, as Defense Minister Guido Crosetto put it.

Russian military bases in Syria appear to be being packed up and evacuated. If Russia relocates to Libya, experts worry the shift could impact security in the Mediterranean and unbalance the frozen conflict there.

After the fall of the Assad regime, Russian cargo planes flew equipment from Syria to bases Moscow controls in eastern Libya, according to U.S. and Libyan officials.

While the Russian military continues to withdraw equipment and troops from Syria, Israel has continued its air raids, intended to further degrade what is left of the former Syrian Armed Forces’ fighting capacity.

Russia is transferring advanced air defense systems and military equipment from its military base in Syria to Libya.
